What's new to me from this piece is that Judge John Coughenour granted a motion request to subpoena e-mail providers Yahoo! and Google in search of Viodentia's identity. If that yields a relevant IP address, Microsoft is permitted to issue subpoenas to the ISP that operates or issued that IP address in order to determine the identity of Viodentia. Engadget says Viodentia claims to live outside of the U.S. If this is true, none of these subpoenas should amount to anything.
